Also on the notion of CPU, for FSX specifically you are better of with higher frequency dualcore than lower frequency quadcore, due to its old core architecture.
There really are different schools of thought on this, and it depends on several factors, wether a higher frequency dual-core is better than a lower frequency multi-core. It depends on the generation of the Northbridge/Southbridge chipsets that you are using on your computer's motherboard, FSB speed, RAM clock speed, DMA
clocking and else.
An important thing is wether the software/OS is aware of the multi-cores and can really make use of them.
For example, out of the several machines that I use on a daily basis for my work, two of them that I run FSX on, one is a genuine 8-CPU Intel XEON based 64-bit machine with 64GB of DDR3 RAM, and another is my personal laptop with a 4-core Intel i7 64-bit processor with dual threads per core and 16GB of DDR3 RAM.
FSX and the underlying OS
(depending on which) can take advantage of either the true 8-CPU machine or the 4-core w/dual threaded architecture, in varying operating modes.
So in many cases, a well written multi-core-aware application can work better on a slower clocked CPU than just throwing more GHz at the problem.
But still, one cannot dismiss the value of a decent GPU and a decent amount of RAM. And a decently fast HDD/SSD.
Still - many factors to consider.
